Hypertrophic obstructive cardiomyopathy complicated by ruptured chordae tendinea to the posterior mitral leaflet and severe congestive heart failure

Abstract

A 63-year-old woman with hypertrophic obstructive cardiomyopathy developed rapidly progressive fatigue, shortness of breath and congestive heart failure. A transesophageal echocardiogram demonstrated ruptured chordae to the posterior mitral valve leaflet with severe mitral regurgitation. Mitral valve replacement eliminated the outflow gradient. Acute or subacute hemodynamic deterioration in a patient with hypertrophic obstructive cardiomyopathy should lead to a search for associated lesions.

Une femme de 63 ans ayant une myocardiopathie obstructive hypertrophique s’est mise à présenter une lassitude, un essoufflement et une insuffisance cardiaque congestive à évolution rapide. Un échocardiogramme transœsophagien a démontré une rupture des cordons tendineux du feuillet valvulaire mitral postérieur accompagnée d’une grave régurgitation mitrale. Le remplacement de la valvule mitrale a éliminé le gradient d’éjection. La détérioration hémodynamique aiguë ou subaiguë des patients ayant une myocardiopathie obstructive hypertrophique devrait susciter la recherche de lésions connexes.
